Research On The Evaluation Of Chemical Equilibrium Thought Level

With the reform of the chemistry curriculum,the construction and implementation of the core literacy system is regarded as the backbone of the education and curriculum reform.In view of the fact that the thought of chemical equilibrium is a must-have thought for students,this paper takes the high school students' level of chemical equilibrium as the theme,and analyzes the level of high school students' chemical equilibrium thoughts through evaluation.Based on the "High School Chemistry Curriculum Standards(2017)",this paper takes the academic quality level in the Chemistry Curriculum Standards as the evaluation dimension,combined with the recent chemical-equilibrium-related college entrance examination questions,based on the students' existing cognitive structure,starting from the various levels of academic quality.The equilibrium of thoughts was assessed by a chemical equilibrium thought test paper on a four-star high school Grade 2 and Grade 3 students.The results of the evaluation were analyzed using SPSS 23.0.A comparative analysis of the literacy level of the chemical equilibrium in the High School Chemistry Curriculum Standards(2017)to determine the level of students' chemical equilibrium thoughts,and concludes that:(1)The overall level of high school students' chemical equilibrium thought is not high.Among them,the average level of high school Grade 2 students' chemical equilibrium thought is at level 2 and slightly higher than this level.The average level of high school Grade 3 students' chemical equilibrium thought is at level 3,and slightly higher than this level,not reaching level 4.(2)The level of chemistry equilibrium of high school Grade 3 students is higher than that of high school Grade 2 students.The thought of high school students' chemical equilibrium grows with ages.(3)The gender difference in the level of high school students' chemical equilibrium is not obvious.In response to the above conclusions,the study proposes the following recommendations:(1)Establish a chemistry teaching philosophy centered on core literacy.(2)Establish a simple and effective chemical core literacy evaluation system.(3)Implement the cultivation of chemical core literacy in the teaching process.The results of this research are as follows:(1)define the meaning of the idea of chemical equilibrium.(2)Construct a structural framework for the evaluation of the level of chemical equilibrium.(3)Develop a tool for assessing the level of chemical b equilibrium.(4)Reveal the chemical equilibrium of high school students.At the same time,this study also has the following shortcomings:(1)Due to limited conditions,the sample size is small.(2)Only one of the chemical core literacies is studied.(3)The processing of the evaluation data is relatively simple.
